Get in trouble a little bit (5)
I believe the answer is:
tinge
'a little bit' is the definition.
(a tinge is a little bit)
'get in trouble' is the wordplay.
'trouble' indicates anagramming the letters.
'get'+'in'='getin'
'getin' is an anagram of 'TINGE'.
(Other definitions for tinge that I've seen before include "suggestion" , "Colour slightly; trace" , "Suffuse" , "A smack" , "A suspicion" .)
